A Mathematical Study of Hawking Radiation on Collapsing, Spherically Symmetric Spacetimes
… give a mathematical treatment of the late time Hawking radiation of massless bosons emitted by a family of collapsing, spherically symmetric, charged models of black hole formation, including both extremal and sub-extremal black holes. We further bound the rate at which the late time behaviour …

Semi-classical aspect of black hole physics
… physics are studied with particular emphasis on Hawking radiation and its derivation from tunnelling method techniques.

Fermion Quantum Field Theory In Black-hole Spacetimes
… theory ensures the thermal character of the Hawking radiation. In our case, we compute and prove that the spectrum of neutrinos emitted from a black-hole via the Hawking process is indeed thermal. We also study fermion scattering amplitudes off the Schwarzschild black-hole.

Two quantum effects in the theory of gravitation
… is saved, however, by the inevitable presence of Hawking radiation in the quantum theory.

EXPLORATIONS IN QUANTUM GRAVITY AND CONFORMAL BOOTSTRAP
… the replica trick for computing the entropy of Hawking radiation, we found a new saddle-point in the gravitational path integral. This saddle-point corresponds to a wormhole solution connecting different replica sheets. By including this saddle, we showed that the entropy computation is …

Simulation of curved-space quantum field theories with two-component Bose-Einstein condensates: from black-hole physics to cosmology
… We first consider black-hole related phenomena (Hawking radiation and rotational superradiance) that have already been analysed with single-component systems, generalising the results to mixtures; we then proceed to tackle a problem (the decay from the false vacuum) which instead requires the …

Radiation of strongly interacting particles by thermal sources: Violation of the Stefan-Boltzmann law
… emitted from a hot thermal source by means of Hawking radiation could self- interact. With such strong interactions, the Stefan-Boltzmann law would not accurately describe the properties of the radiation. This thesis discusses two different regions of a strongly interacting gas around a thermal …

Production and evaporation of higher dimensional black holes
… and angular momentum loss into gravitational radiation is described. A detailed study of the effects of particle mass and charge, for fermions and scalars on the effective brane charged background, is presented in chapters 5 and 6. After coupling the fields to the background, the separated …

A study of the feasibility of detecting primordial microscopic black hole remnants with the NOvA far detector
Several papers have argued that microscopic black holes may be stable against complete evaporation and may be a viable dark matter candidate [1–3]. This paper assesses the practicality of detecting these objects using long-baseline neutrino facilities, such as the NuMI Off-Axis νe Appearance (NOvA) …

Topological phases, non-equilibrium dynamics and parallels of black hole phenomena in condensed matter
… parallels of black hole phenomena such as the Hawking-Unruh effect and quasinormal modes in quantum Hall systems. The Hawking-Unruh effect is the emergence of a thermal state when a vacuum of a quantum field theory on a given spacetime is restricted to a submanifold bounded by an event horizon. …

Global dynamics of the universe
… these equations. also discuss the occurrence of Hawking radiation in topologically different black-hole geometries. Furthermore, we study the relation between black-hole solutions and circular cosmic strings. Assuming the existence of circular 1 cosmic string with deficit angle ranging between 0 …
